Earlier, I tried reversing the order of the vertically flipped 'rear' neck, and they were still annoyingly in sync. I finally realized that I had to move the middle frames to the ends and the end frames to the middle to get them the way they are up there.

Now I realize that I should reverse the order on the rear neck because I want that sudden lurch forward to be the same front and back

...BUT I'M DONE WITH IT NOW ...REALLY! I don't have to work on it anymore :P
